1pt A cannon fires a 5-kg ball horizontally from a muzzle that is 1 m above the ground. The
velocity of the ball on leaving the cannon is 700
m/s. At the same time that the cannon is fired,
a soldier drops an identical ball straight down
from a height of 1 m. Neglecting friction and air
resistance, which statement is correct regarding
when the balls strike the ground?

Which statement about covalent bonds is true

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?
